01 tapered outer spherical ball bearing tapered spherical ball bearing its insulation structure, code-named: UK200 series, UK300 series.
Such outer spherical ball bearing inner taper hole for 1:12 share, apply to cooperate with tight sleeves when use, this kind of outer spherical ball bearing features as follows: insert ball bearing units can accept than covered wire larger load.
As working with tight sleeves outside diameter than covered wire of the same type spherical ball bearing, insert ball bearing units for covered wire UC209 diameter of 45 mm, instead of the cooperation use the diameter of the shaft was 45 mm, but if if insert ball bearing units with tapered, can only choose the inner diameter of 45 mm set, and cooperation with 45 mm set set of tapered outer spherical ball bearing is only UK210 (
Of course, if agree with higher can choose UK310)
。
Thus, acceptable UK210 fit when make a much bigger than UC209.
Outside the spherical bearing insulation structure between bearing and floor must be pad with insulation plate or metal gasket, metal gasket used to adjust the horizontal position.
To adjust the motor and the coupling of another or mechanical relative position.
Metal gasket is by 0.
08 ~ 3 mm is made of sheet metal.
The insulation plate is made from or fiber glass cloth laminated sheet made of the laminate.
Put insulation plate purpose mainly is to prevent the harm of shaft current.
Insulation plate should be than bearing on each side of 5 ~ 10 mm wide, thickness is 3 ~ 10 mm.
Besides placed between the bearing and floor insulation plate, at the same time to nail screw and stability should be insulated.
Insulation gasket made of 2 ~ 5 mm thick plate glass cloth, its diameter is larger than iron ring diameter 4 ~ 5 mm.
Connects with the bearing oil pipe flange insulation pad can be used for 1 ~ 2 mm thick rubber sheet.
Bearing of the insulation after installation should check the insulation resistance, measured with 500 v megohmmeter, its value should not be less than 1 megohm.
